Google Glass and the Digital World

Many millions of people depend on Google to search, collect and organize data, for email and smart phones…and Google's found ways to turn all that information into billions of dollars. But Google has already demonstrated that what it gives it can take away. Now comes a new advance in personalized technology. Select people -- including one of today's guests -- are testing out Google Glass. Glance up and there's computer data in front of your eye. Ask a question, get an answer: Where's the bank or the restaurant?  How does this price compare?  Well and good, if you don't run into a door. But who am I talking to? That raises more questions than answers about privacy, social interaction and the influence of digital networks on daily life. Is Google Glass a step toward brain implants and computer control?  Is Google losing its cool?
